Detailed Description

Macro Definition Documentation

◆ SIP_ACCEPT_LANGUAGE_INIT

#define SIP_ACCEPT_LANGUAGE_INIT ( )

Initializer for structure sip_accept_language_t.

A static sip_accept_language_t structure for Accept-Language header must be initialized with the SIP_ACCEPT_LANGUAGE_INIT() macro. For instance,

#define sip_accept_language(sip)
Access a SIP Accept-Language header structure sip_accept_language_t from sip_t.
Definition sip_protos.h:7509
#define SIP_ACCEPT_LANGUAGE_INIT()
Initializer for structure sip_accept_language_t.
Definition sip_protos.h:7526

◆ SIPTAG_ACCEPT_LANGUAGE

#define SIPTAG_ACCEPT_LANGUAGE (   x)

Tag list item for pointer to a Accept-Language header structure sip_accept_language_t.

The SIPTAG_ACCEPT_LANGUAGE() macro is used to include a tag item with a pointer to a sip_accept_language_t structure in a tag list.

Parameters
xpointer to a sip_accept_language_t structure, or NULL.

The corresponding tag taking reference parameter is SIPTAG_ACCEPT_LANGUAGE_REF().

◆ SIPTAG_ACCEPT_LANGUAGE_STR

#define SIPTAG_ACCEPT_LANGUAGE_STR (   s)

Tag list item for string with Accept-Language header value.

The SIPTAG_ACCEPT_LANGUAGE_STR() macro is used to include a tag item with a string containing value of a sip_accept_language_t header in a tag list.

Parameters
spointer to a string containing Accept-Language header value, or NULL.

The string in SIPTAG_ACCEPT_LANGUAGE_STR() can be converted to a sip_accept_language_t header structure by giving the string s has second argument to function sip_accept_language_make().

The corresponding tag taking reference parameter is SIPTAG_ACCEPT_LANGUAGE_STR_REF().

Function Documentation

◆ sip_accept_language_copy()

sip_accept_language_t * sip_accept_language_copy ( su_home_t home,
sip_accept_language_t const *  hdr 
)
inline

Copy a list of Accept-Language header header structures sip_accept_language_t.

The function sip_accept_language_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.

Parameters
homememory home used to allocate new structure
hdrpointer to the header structure to be copied

When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.

Example
accept_language = sip_accept_language_copy(home, sip->sip_accept_language);
sip_accept_language_t * sip_accept_language_copy(su_home_t *home, sip_accept_language_t const *hdr))
Copy a list of Accept-Language header header structures sip_accept_language_t.
Definition sip_protos.h:7656
Returns
A pointer to newly copied header structure, or NULL upon an error.

◆ sip_accept_language_dup()

sip_accept_language_t * sip_accept_language_dup ( su_home_t home,
sip_accept_language_t const *  hdr 
)
inline

Duplicate a list of Accept-Language header header structures sip_accept_language_t.

Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next) to a list of headers, all the headers in the list are duplicated, too.

Parameters
homememory home used to allocate new structure
hdrheader structure to be duplicated

When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.

Example
accept_language = sip_accept_language_dup(home, sip->sip_accept_language);
sip_accept_language_t * sip_accept_language_dup(su_home_t *home, sip_accept_language_t const *hdr))
Duplicate a list of Accept-Language header header structures sip_accept_language_t.
Definition sip_protos.h:7613
Returns
A pointer to the newly duplicated sip_accept_language_t header structure, or NULL upon an error.

◆ sip_accept_language_format()

sip_accept_language_t * sip_accept_language_format ( su_home_t home,
char const *  fmt,
  ... 
)
inline

Make a Accept-Language header from formatting result.

Make a new sip_accept_language_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_accept_language_t.

Parameters
homememory home used to allocate new header structure.
fmtstring used as a printf()-style format
...argument list for format
Returns
A pointer to newly makes header structure, or NULL upon an error.

◆ sip_accept_language_init()

sip_accept_language_t * sip_accept_language_init ( sip_accept_language_t  x[1])
inline

Initialize a structure sip_accept_language_t.

An sip_accept_language_t structure for Accept-Language header can be initialized with the sip_accept_language_init() function/macro. For instance,

sip_accept_language_t sip_accept_language;
sip_accept_language_t * sip_accept_language_init(sip_accept_language_t x[1])
Initialize a structure sip_accept_language_t.
Definition sip_protos.h:7544

◆ sip_accept_language_make()

sip_accept_language_t * sip_accept_language_make ( su_home_t home,
char const *  s 
)
inline

Make a Accept-Language header structure sip_accept_language_t.

The function sip_accept_language_make() makes a new sip_accept_language_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.

Parameters
homememory home used to allocate new header structure.
sstring to be decoded as value of the new header structure
Returns
A pointer to newly maked sip_accept_language_t header structure, or NULL upon an error.

◆ sip_is_accept_language()

int sip_is_accept_language ( sip_header_t const *  header)
inline

Test if header object is instance of sip_accept_language_t.

Check if the header class is an instance of Accept-Language header object and return true (nonzero), otherwise return false (zero).

Parameters
headerpointer to the header structure to be tested
Return values
1(true) if the header is an instance of header accept_language
0(false) otherwise

Variable Documentation

◆ sip_accept_language_class

msg_hclass_t sip_accept_language_class[]
extern

Header class for Accept-Language header.

The header class sip_accept_language_class defines how a SIP Accept-Language header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_accept_language_t header structure.
